The above numer 0-280-150-403., shows the following,
FLOW= LBS/HR 47.9, CC/MIN = 503.4, GRAMS/MIN 362.1
Rating 43.5 PSI/3 BAR, these are LOW impedance injectors fitted as standard kit to FORD 5.0i HO.
The listing also contains BSFC data, not really of any use.
NOTE:
THERE IS ANOTHER INJECTOR OF THE EXACT SAME NUMBER, which has different flow, but this is most likely due to a pressure increase, as the flow is higher.
